G. K. Chesterton: The Innocence of Father Brown

5. The Invisible Man (continued)

"It's the writing of that fellow Welkin," said Smythe gruffly. "I haven't seen him for years, but he's always bothering me. Five times in the last fortnight he's had threatening letters left at my flat, and I can't even find out who leaves them, let alone if it is Welkin himself. The porter of the flats swears that no suspicious characters have been seen, and here he has pasted up a sort of dado on a public shop window, while the people in the shop--"

"Quite so," said Angus modestly, "while the people in the shop were having tea. Well, sir, I can assure you I appreciate your common sense in dealing so directly with the matter. We can talk about other things afterwards. The fellow cannot be very far off yet, for I swear there was no paper there when I went last to the window, ten or fifteen minutes ago. On the other hand, he's too far off to be chased, as we don't even know the direction. If you'll take my advice, Mr. Smythe, you'll put this at once in the hands of some energetic inquiry man, private rather than public. I know an extremely clever fellow, who has set up in business five minutes from here in your car. His name's Flambeau, and though his youth was a bit stormy, he's a strictly honest man now, and his brains are worth money. He lives in Lucknow Mansions, Hampstead."

"That is odd," said the little man, arching his black eyebrows. "I live, myself, in Himylaya Mansions, round the corner. Perhaps you might care to come with me; I can go to my rooms and sort out these queer Welkin documents, while you run round and get your friend the detective."

"You are very good," said Angus politely. "Well, the sooner we act the better."

Both men, with a queer kind of impromptu fairness, took the same sort of formal farewell of the lady, and both jumped into the brisk little car. As Smythe took the handles and they turned the great corner of the street, Angus was amused to see a gigantesque poster of "Smythe's Silent Service," with a picture of a huge headless iron doll, carrying a saucepan with the legend, "A Cook Who is Never Cross."
